I'm having the same problem.
1. I create a simple gadget and put up at
http://my.host.server/sample.xml
2. I verify the URL is accessible from another machine.
3. I add the app's URL to my Orkut sandbox account.
4. I go to the verification page, get the token, copy it into my
gadget's CDATA, save, and download the gadget to verify it has been
updated.
5. I then click the "verify" button, but I always get the message that
the verification failed.
I've tried several times with no luck.
Thanks for any help--
